Python 2.7 I noticed a recurring bug we've had attempting to send a particular JPEG image in emails: email.mime.image.__init__ <unknown>: Could not guess image MIME subtype After looking into the imghdr.what and tests source code, I noticed that this JPEG image begins with the following data: '\xff\xd8\xff\xee\x00\x0eAdobe\x00d\x00\x00\x00\x00\x00\xff\xed\x008Photoshop ' I've attached the image in question to this bug report. There's two functions for asserting an image is JPEG format, test_jpeg and test_exif. I'd like to propose another function for resolving Adobe Photoshop image formats. Unless, of course, this is expected behavior? Thanks! |

Well, it's 'expected' behavior in the sense that we don't know about 'adobe' format. Is there some better way to detect jpeg format than to look for particular format identifiers in a specific byte position? |

Issue issue16512 has a patch which will recognize this format of JPEG, as well as others. |

Closing this in favor of issue 16512, which I will expand to include this case. |
